Aston Martin DB9 2dr Coupe 6.0 V12, Volante 6.0 V12 (2004-2012, AM11 & AM11A)
Failure mileage range
40,000-80,000 miles
Typical failure window
Root cause
Hydraulic lash adjusters wear or fail, causing persistent ticking; on early Cosworth AM11 blocks, oval cylinder bore wear exacerbates the issue.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Lash Adjuster Replacement | £3,500 - £6,000 | £2,200 - £4,000 | Remove valve covers, replace faulty hydraulic lash adjusters, reset timing | May resolve ticking if caught early; not viable if oval bore wear present |
| Intermediate - Top-End Rebuild | £8,000 - £14,000 | £5,500 - £9,500 | Strip cylinder heads, replace adjusters, valves, seals; machine heads if needed | Addresses valve-train issues; does not fix bottom-end or bore problems |
| Full Replacement - Rebuilt / Reconditioned Engine | £25,000 - £35,000 | £17,000 - £27,000 | Supply & fit of fully rebuilt V12 with upgraded components addressing original failure points | Comprehensive solution; includes 12-month warranty; recommended for high-mileage or bore-wear cases |
Our recommendation
On a DB9 worth £25,000-£45,000, if ticking is accompanied by low compression or oil consumption, full replacement is often more cost-effective than repeated top-end repairs. For early Cosworth AM11 blocks, specialist assessment for oval bore is essential before committing to any repair.
